The story centers on Kakeru Satsuki, a seemingly ordinary high school student who suffers from amnesia and has lost all memories of his past. He lives a normal life until a supernatural event plunges him and his friends into a dangerous alternate dimension known as the Red Night. In the Red Night, ordinary people encounter terrifying monsters and hostile forces that seem intent on killing them. Those who enter the Red Night must fight to survive, but the city itself behaves strangely, as if governed by its own malevolent will.
Kakeru Satsuki has been living a boring, ordinary life ever since his sister committed suicide seven years ago. However, one day, he and his best friend Yuka Minase are suddenly transported to an alternate reality where the sky is filled with dark, crimson clouds, a black moon and terrifying creatures lurk.
Kakeru and Yuka are in the Red Night dimension again and this time they meet a strong young woman named Misuzu Kusakabe, who saves them from a horde of the evil blob like creatures, and find a girl trapped in a crystal. They are attacked by some other strong creatures and then find themselves back in the normal world. Can they discover the mystery behind the Red Night and why only certain people are taken there?
Kakeru wants to protect Yuka no matter what but he just can't seem to find his power and sure enough, they are tranported once again to the Red Night and now Kakeru is facing one of the Black Knights and must defeat it. Can Kakeru awaken his power in time to save Yuka?
Yuka has finally awakened her power and she wishes to protect Kakeru by using it but Kakeru does not want her to use her power because he fears that it could harm her. Meanwhile, the Black Knight, Superbia, has a plan to eliminate the "fragments." What is her plan and why is Shiori acting strangely?
